Award-winning Vanity Fair writer Nancy Jo Sales crisscrossed the country talking to more than two hundred girls between the ages of thirteen and nineteen about their experiences online and off. They are coming of age online in a hypersexualized culture that has normalized extreme behavior, from pornography to the casual exchange of nude photographs; a culture rife with a virulent new strain of sexism; a culture in which teenagers are spending so much time on technology and social media that they are not developing basic communication skills.

The dominant force in the lives of girls coming of age in America today is social media: Instagram, Whisper, Vine, Youtube, Kik, Ask.fm, Tinder.

Provocative, explosive, and urgent, American Girls will ignite much-needed conversation about how we can help our daughters and sons negotiate the new social and sexual norms that govern their lives.
